The advice I have for younger kids navigating social media is , you should always try to be careful with what you watch and browse, if something is scary you should always try to reach out to someone you trust. A lot of things are scary but you don’t have to go through things alone, You should never talk to someone online that you don’t know without asking your parents & even though you think you are grown up and think you are mature to watch things like horror and ETC, you aren’t. There are some things you aren’t ready for and especially watching videos you aren’t supposed to or even talking to people you don’t know.
